A method of wireless transmission applicable to transmission between a first communication terminal and a second transmission terminal is provided. The first communication terminal transmits data via a first channel selected as a primary transmission channel. The transmission quality of the primary transmission channel is detected. When it is determined that the quality of the primary transmission channel degrades, a third channel replaces the first channel as the primary transmission channel, and a replacement request is sent from the first communication terminal via a second channel. The first communication channel then transmits data via the third channel as the primary transmission channel.

Wireless transmission method and associated system

A portable electronic device having automatic power supply mode switching is provided. The portable electronic device includes a micro-sensor and a control circuit. The control circuit controls operations of the electronic device, the micro-sensor senses whether the electronic device is carried or worn by a user. When the electronic device operates in a normal mode, and if the electronic device is not carried or worn for a time longer than a buffer period of a predetermined interval, the control circuit switches to a sleep mode, which results in lower power consumption.

Automatic mode switch portable electronic device

An integrated circuit chip is provided. The integrated circuit chip includes a pad, a first resistor, a second resistor, a first switch, a second switch and a controller. The first resistor and the first switch are serially connected between the pad and a first reference voltage terminal. The second resistor and the second switch are serially connected between the pad and a second reference voltage terminal. The controller selectively turns on and off the first and second switches according to an error determining mechanism. The error determining mechanism determines whether an error condition associated with the pad is present.

Integrated circuit chip and testing method capable of detecting connection error

An image scaling system includes a window memory, a longitudinal scaler, a buffer and a latitudinal scaler. The window memory temporarily stores partial data of N image lines. The longitudinal scaler performs a longitudinal scaling operation on the partial data of the N image lines to thereby produce partial data of a longitudinal image line. The latitudinal scaler performs a latitudinal scaling operation on the partial data of the longitudinal image line to thereby produce scaling-part data of a latitudinal image line. The longitudinal scaler and the latitudinal scaler use a window average to perform an image shrinking operation and a bi-linear interpolation average to perform an image expanding operation.
